To all whom, it may concern,.-

Be it known that I, ETHAN I. Donne, of Avalon, Allegheny county, Pennsylvania, have invented a new and useful Improvementin Car Parts, of which the followingis a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in whicl1- Figure l shows in. plan View a channelbeam which has been cut and pressed later* ally for the purpose of producing ra brakebeam in accordance with my invention. Fig. 2 is a side elevation thereof. Fig. 3 is a ver* tical section on the line I Il III of Fig. 2. Fig. 4 is a side elevation illustratinfr a modified construction in which the middle member has a flange deeper a* the middle than at the end portions and the flanges are directed downwardly. Fig. 5 is a View similar to Fig. 4C, showing a modification in which the flanges are directed upwardly. Fig.. 6 is a lvertical section on the line VI VI of Fiv. 5. Figs. 7 8 and 9 are plan Views of modified constructions ofthe brake-beam with the top member removed for purposes of illustration, Fig. 7 beine' a plan View of Fig. 2, Fig. 8 a lan View o? Fig. 4, and Fig. 9 a plan View of ig. 5. Fig. l() illustrates a modification in which the top and bottom members of the brakebeam are bent. Fig. 11 is a Vertical section on the line XI XI of Fig. 10. Figs. 12, 13, and 14 are views similar to Fig. 10, illustrating modifications. Fi s. 15, 16, and 17 are sections on the lines X I, XVI, and XVII of Fi s. 12 to le, respectively.

lhe purpose of my invention is to manufacture brakefbeams, bolsters, and other parte of?l railway-cars from metal pieces with as little possible waste of metal and with great strength and rigidity-oi' construction. The saving which I thus obtain is very oonsiderable, since heretofore the waste incident to the cutting and shaping of the parts ofcars has constituted a largo item of cost.

`My invention consists in Vforming a car part, which may be a brake-beam, bolster, or other part oi a car, by cutting through the middle portion. oi.' a metal piece so'as to form a middle menibei',"then separating such iniddle member transversely awayfrom the side members and compensating for the slierten- .ing of the metal piece,'preferably by bending produced by the cutting operatiomeither away from the middle 1nc1nber or laterally toward each other, so as to accommodute them to the deflected position oli the middle member.

On Sheet l of the drawings, which illustrates the manner of making a brake-beam in accordance with :my invention, I show a flanged metal piece, which may be an I-beam or a channel-beam and indicated by the dotted outline in Fig. l, and l slit it longit udinally through the web by two parallel cuts b l. Then by means of suitable dies or other apparatus I bend the out beam into the shape shown in Fig. 2, bending the middle portion e downwardly and the two side members d d toward each other, so as to compensate for the shortening ol the section produced by the down-bending of the middle member tc. I also flange the middle member c, as indicated in Fig. 3, preferably by the same dies and at,

the same operation as that in which it is bent downward y. In Fig. 2 I show this flange as beine" oi uniform depth from end to end oi' the middle member.

Fig. 3 illustrates in full lines the shape to which the article is brought by the operations above described and by dottedv line shows the original position of the side members d d before the bending operation.

In Figs. l and 8 the brake-beam is con structed as above described, except that the middle member c is flanged with outwardlydirected ilanges which are deeper at the mid die than at the ends, and' said member c therefore has the tapering form in plan View as shown in Fig. 8. The construction showii .in Figs. 5, 6, and 9 is the saine as in Fig. a, except that the flanges of the middle member arcinwardly directed.

The brake-beam made as above described may be fitted with the usual irons and attacliments.

In the figures shown in the second sheet of the ('hawings instead of bending the side members d d, here marked d d', laterally toward each other I bend thorn upwardly and away 'from the middle member c for the pur- .pos'e of compensating for the shorteniner oi the metal consequent upon the bending oithe member c. In Figs. l() and 11 thelbrake` beam thus made is constituted of' a el1annelsection slit longitiuiinally through the web,

"as shown ,in 1., the parts thus slit being i bent 1n opposite dniuftions'jthe bor c being flanged downwardly, and tll'e IOC middle mem-a franges being of uniform depth from end to end. In the construction shown in Figs 12 and 13 the angesof the member c are deepest at the middle, and in the construction shown in Figs. 13 and 17 they are inwardly directed.-

InFigs. 14 andfl? I show the brake-beam when made from an I-beam section. In Figs'` 14 and 17 the middle member c is flanged and' the flanges'directed outwardly.

I-'bcams may be substituted for channels in any of the constructions shown in the drawings, and the middle member of anyof them-may be flan ed in either direction.

In the figures a ov described the shortening of the metal followed by the bendingof the middle member is compensated bythe corresponding bending of the side members, either in a direction toward each other or in a direction away Jfrom the middle member.

The foregoing description will show that my invention may be modified in many Ways within the definition of the claims and that it may be adapted to the manufacture of beams, transoms, bolsters, end sills, etc., of dilierent ty es, since 1. A car part composed of a flanged metal piece slit in the Wet with longitudinal slits to afford a middle member and side members, said middle memberand side members being'bent away from eachother in ,a directionv transverse to the web, and the middle member being flanged; substantiallylas described 2. A car part composed of a anged metal piece slit in the web with lon itudihal slits toi aord .a middle member an 4side mmberg said middle member and side membersbeing b ent away from each other in a4 direction transverse to the web, andthe middle member being flanged with Han esv deeper at the -Iniddle portion; substantial descibed. l

a ange meta "'lcar part composed 'o Y piece slit in the web with longitudinal slits to afford a middle .member and side members, said middle member and side members being bent away from eachv other in al direction transverse to the-Web, and the side members being bent'toward each other in the same plane; substantially as described.

In testimony whereof I have hereunto set my hand February 20, 1904. i
